0% of those kill a ship outright.
They don't need to (for the most part).
I've been on receiving end of all of the weapons about enought that I can tell you how hard it is to deal with damage when you get hit consistently with these weapons (after all you need to consistently with with artemis or gatling consistently for them to be effective).
6 clip of LJ will kill pyra's baloon AND armor. Point short range hawcha with burst ammo will kill EVERYTHING except baloon on Pyra (double hawacha hit WILL outright kill a Pyra).
Heavy Carrorade will keep enamy ship dropping (you generaly loose about 170M height if you loose baloon and have engineer with spanner camping it - that is enough to keep enemy out of the combat to punt the other enemy in dire straits in 2v1.
And heavy flak will outright murder you if loose armor.
As for Typon's smaller brother Echidna light flak: it's a perfect engineer's and pilot's gun - it has incredible burst damage, and it takes very short time to fire all your shots, and then you are back your job. You just can't waste any shots on armor or by missing (hitting with echidna is pretty easy).
